Abstract: A plug for retaining wire on a substantially vertical elongate post having an inverted substantially L-shaped slot that opens into a substantially horizontal elongate wire-introducing portion and ends in a substantially vertical elongate wire-retaining portion, wherein the plug is adapted to friction fit in the wire-introducing portion to substantially horizontally overlap wire previously received in wire-retaining portion.

Abstract: A gaming system (1) comprising an electronic gaining machine (5) having an associated players station interface device (4) configured to monitor the turnover of the electronic gaming machine (5) and having an interface device display (7) configured to display an interface device electronic game such that a predetermined proportion of the electronic gaming machine turnover is pulled into an interface device electronic game jackpot controlled by a control server (2) in communication with the player station interface device (4) wherein an electronic trigger is sent from the control server (2) to the player station interface device (4) to commence an interface device game and wherein the control server (2) is configured to provide a payout for a user winning the interface device game.

Abstract: A hand tool grinding jig is described for use in co-operation with a grinding wheel. The jig has a tool clamp for clamping a hand tool and a leg is pivotally connected to the clamp to allow the angle between the leg and the clamp to be adjusted. An end of the leg remote from the clamp provides a pivot point for engagement in a pivot receiver of a pivot support member that is located adjacent to the grinding wheel. The pivot receiver is disposed so that, when a tool is in the tool clamp and the pivot point is provided in the pivot receiver, the pivotal axis between the leg and the clamp is further from the grinding wheel than the pivot receiver.

Abstract: The present disclosure relates to a disinfecting compositions of pH 2-7 comprising:a) 1-30 wt. % on product of an ethoxylated nonionic surfactant;b) less than 50 wt. % of total surfactant of anionic surfactant;c) 0.005-5 wt. % on product of a water-soluble, anionic polymer having an average molecular weight of less than 1,000,000, wherein, the ratio of polymer: nonionic is 0.1:1 or less; andd) 0.1-15 wt. % on product of an antimicrobial agent selected from the group comprising:i) benzoic acid derivatives, dicarboxylic acids, C.sub.1 -C.sub.6 alkanols and mixtures thereof.

Abstract: A casino dolly for use in a roulette game includes sensors, preferably using passive infra red detection, to detect the presence of a hand or movement of chips in an area around the dolly. When the dolly is placed on the area of a winning number on a roulette board it will act to set off an alarm if the sensors detect an attempt to place late bets in the area around the dolly.

Abstract: Granular laundry detergent compositions containing peroxyacid bleach and anionic, sulfobenzoyl end-capped esters useful as soil release agents. The terephthalate esters contain oxyethyleneoxy and oxy-1,2-propyleneoxy units, and are substantially amorphous in form.

Abstract: Described are laundry detergent compositions containing nonionic surfactants, cationic surfactants and compatible anionic brighteners which are highly effective at whitening cotton fabrics.

Abstract: A coating composition for glass fibres intended for use as reinforcement in cementitious products is disclosed, which contains at least one monocyclic or polycyclic aromatic compound having at least three hydroxyl groups on the aromatic ring or (in a polycyclic compound) on at least one of the aromatic rings, together with at least one partially-cured A-stage phenolformaldehyde resin of the water-dilutable resole type.

Abstract: A method is disclosed for oxidation of finely-divided sulphide ores or mattes containing iron, with one or more of the elements nickel, copper, cobalt, zinc and lead as constituents, in the presence of iron chloride in an oxygen-containing atmosphere at a temperature of 220.degree.-400.degree. C, to convert the mixture of iron chlorides and sulphides to water-insoluble iron oxide, the nickel, copper, cobalt and zinc being converted to water-soluble chlorides and sulphates, and the lead to a sulphate which may be leached away from the residual iron oxide by special solvents for lead sulphate. The initial iron chloride is preferably obtained by adding aqueous hydrochloric acid to the concentrate, if iron sulphide is present in a susceptible form, to drive off a portion of the sulphide sulphur as hydrogen sulphide gas, and to convert the corresponding iron sulphide to iron chloride. Temperatures may rise as high as 450.degree. C during the roasting phase if special conditions are observed while cooling.

Abstract: An improved method for agglomerative fluid bed roasting of metal sulphide particles. The sulphide particles are fed as an aqueous slurry through the freeboard of the roaster onto the surface of a bed of roasted calcine agglomerate particles fluidized by a free oxygen-bearing gas. Slurry water is evaporated in the bed and the sulphides are roasted therein. The feed rates of sulphide, water and free oxygen-containing gas are controlled to ensure temperatures in the roaster such that fusion occurs during roasting and agglomerated calcine particles are formed with regular, rounded surfaces. Calcine particles small enough to become entrained in the roaster off-gases are readily disengaged therefrom in cyclones to provide substantially dust-free SO.sub.2 -bearing gas. A preferred practice of the method is feeding substantially the stoichiometric amount of free oxygen to convert the sulphide to SO.sub.

Abstract: A d.c. motor control system includes a pair of armature windings mounted on a single rotor or on a pair of mechanically coupled rotors, and a field winding or windings. The system includes switch means operable to effect a change in the electrical connections of the armature windings to a pair of electrical supply terminals and means for effecting variations of the current flowing in the field winding or windings.
